<p>In this note we present an approach to estimate the adjoint sensitivity of wind power generation using numerical weather prediction (NWP) models. This approach augments the planning and operations of wind farms by improving the accuracy of wind forecasts obtained by either physics-based NWP or statistical data-based models. The proposed analysis can be used to determine the simulation domain size and resolution, and suitable observation placement. We illustrate the method of determining sensitivities of wind speed at wind-farm locations with respect to current ambient conditions in a northern Texas region using real data and atmospheric conditions.</p>
